Using C1 v7 on my MacbookPro with 10.6.8, I've disabled the 'open importer when mounting removable media', yet every time I insert a card either from the reader or the built in SD card slot, C1 opens anyway. No offense to C1, but I use Photo Mechanic for my importing and metadata needs and although it's only slightly annoying, I'd prefer C1 to open only when I want to use it.
